rustfmt indents leading section comments to match code indentation, breaking intentional left-aligned vertical alignment

            .with_quic_config(|mut cfg| {
                // ===== Connection Lifespan =====
                cfg.keep_alive_interval = Duration::from_secs(5);
                cfg.max_idle_timeout = 30_000; // ms (30 seconds)
                // ===== Concurrent Stream Limit (QUIC Layer) =====
                cfg.max_concurrent_stream_limit = 10_000;
                // ===== Flow Control =====
                cfg.max_stream_data = 100 * 1024;
                cfg.max_connection_data = 20 * 1024;
                // ===== Protocol Compatibility =====
                cfg.support_draft_29 = true;
                cfg
            })

After running cargo fmt, the comments are indented to match the surrounding code block:

            .with_quic_config(|mut cfg| {
                // ===== Connection Lifespan =====
                cfg.keep_alive_interval = Duration::from_secs(5);
                cfg.max_idle_timeout = 30_000; // ms (30 seconds)
                                               // ===== Concurrent Stream Limit (QUIC Layer) =====
                cfg.max_concurrent_stream_limit = 100;
                // ===== Flow Control =====
                cfg.max_stream_data = 100 * 1024;
                cfg.max_connection_data = 20 * 1024;
                // ===== Protocol Compatibility =====
                cfg.support_draft_29 = true;
                cfg
            })

// ==== Concurrent Stream Limit (QUIC Layer) ==== is not left-aligned

can you optimize this problem?

@cherishman2005 please update the example so that it's a complete code snippet that we can run rustfmt on. Also, what version of rustfmt are you using and are you using any non default configurations?
